Thursday's temperature hit 32 degrees Celsius.
One one hand, that's not as hot as it could have been. On the other hand, that's pretty darn hot, especially if you're 90 years old and running a mile.
With 11 of 24 events held outdoors around Kamloops, many of the 3,700 participants in this week's B.C. Seniors Games have been feeling the heat. Thursday was the hottest it's expected to get, thankfully, and it was hot enough.
"The heat was so dramatic that our opponents retired," said tennis player Doris St Germain of Saltspring Island, pointing to an afternoon walkover victory. "She got really shaky, a headache - it was just way too much heat for her."
The heat just magnifies the struggles facing athletes this week.
Consider spending minutes, or sometimes hours, exerting yourself physically under a blazing sun. That's tough enough for athletes in their teens, 20s or 30s. But the competitors in town this week are between the ages of 55 and 94, with the average age 67.5.
Still, young or old, beating the heat comes down to one thing.
"If an athlete stays hydrated, the heat won't be too big a problem," said Andy Philpot, the director of medical services for the Games. "The biggest thing is to make sure you keep enough fluids in."
Philpot noted that as of late Thursday, there hadn't been many heat-related problems reported, as seniors tend to know enough to keep hydrated.
"There hasn't been anyone in (at Hillside Stadium) because of the heat," said Philpot, the retired former assistant chief for Kamloops Fire and Rescue. "We have a doctor in the clinic and a critical-care paramedic, and they've been flying around to different events. It's been working very well so far.
"But a lot of these people have been competing all their lives, so they know how to look after themselves at an event."
One doesn't plan a multisport event in a place like Kamloops in the middle of August without realizing that heat will be a factor, and the organizers of the Games planned ahead. That involved creative scheduling and Philpot's medical services team, which numbers 85 and pulls volunteers from all walks of the medical and emergency services community.
The 5,000-metre races were held Wednesday morning, before the heat really became a factor, and Saturday's 10,000m, to be held on McArthur Island, will begin at 9 a.m. That wasn't an accident, either. On Thursday, another of the longer track events, the 1,500m, was held around 2 p.m., right in the heat of the day.
"You do feel it. You get a very dry mouth," said 69-year-old Liz Dilasser of Sechelt, who finished second among women in the 1,500m. "When I came on Tuesday, I started to drink gallons. Hopefully I've done it right - I feel great."
Fortunately, getting a senior to compete in the morning isn't a problem.
"Seniors seem to like participating early in the morning so they can be shut down before the heat of the afternoon," Philpot said. "Some of the venues are already shut down, and it's 2 o'clock. . . . They're keeping (athletes) out of the hot part of the day, and that's a big part of the scheduling process."
Some of the venues being used this week seem to feel a little warmer in the sun than others.
Take Hillside Stadium, where the track and field events are held, for example. Perched on a hill above Thompson Rivers University, the track itself can feel like a sauna on sunny, calm days.
Perhaps worse is the Kamloops Tennis Centre, located near Pioneer Park, on River Street. The hard courts are painted blue inside the lines, and green outside.
Like the Australian Open, which is held in January, at the height of the Australian summer, the blue concrete seems to add to the heat.
"When you're standing on the blue part, you can feel the heat bouncing," St Germain said. "As soon as you move to the green part for your rest, you can feel a slight cooling."
But these seniors are tough, and are beating the heat. If only it was that easy to avoid the insects.
"It's been great," Philpot said. "We've been busy, but mostly with minor stuff. We have to tell people to quit feeding the local wildlife - we're getting a lot of wasp stings."
